Kinetic Degradation Fluxion (KDF) Water Filters

Posted on 1/8/2010 by

KDF is an alloy of copper and zinc that is used in most shower filters and some drinking water filters. It removes free chlorine from water by reversing the electrochemical process that originally produced the chlorine. Chlorine is created by separating chloride ions from sodium in a brine solution.

Kinetic Degradation Fluxion (KDF) is a high-purity copper-zinc formulation that uses a basic chemical process known as redox (oxidation/reduction) to remove chlorine, lead, mercury, iron, and hydrogen sulfide from water supplies. The process also has a mild anti-bacterial, algaecitic, and fungicitic, effect and may reduce the accumulation of lime scale.

KDF process media is used in pre-treatment and primary treatment applications to supplement or replace existing technologies in order to extend system life and to reduce heavy metal contamination, chlorine and hydrogen sulfide. It is often combined with other technologies to achieve superior overall results. Because of its effectiveness at higher water temperatures, it is often used on shower water filtration systems to remove chlorine and other contaminants. The technology was developed by KDF Fluid Treatment, Inc. in the mid 1980s and was patented in 1987. KDF filter media meets EPA and Food and Drug Administration standards for levels of zinc and copper in potable water, and is certified by NSF International to its Standard 61 for drinking water.

Kinetic Degradation Fluxicon (KDF) water filters use the Redox (oxidation/reduction) chemical process. Redox works by changing the structure of the damaging contaminants. The structural change is brought about by transferring electrons between two media and creating one positive and one negative charge.

The KDF water filter contains two process media, one with negative charge and the other positive. All chemicals contain atoms, these atoms are also charged either positively or negatively. As the chemical passes through the KDF water filter process positively charged atoms get attracted to the negative charge in the filter and the same happens to negatively charged atoms being attracted to the positive charge in the filter. The transfer of electrons that happen during this process changes the make up of possibly harmful chemicals.

KDF filtration does add trace amounts of copper and zinc to the water. These small amounts of copper inhibit growth of viruses, algae, fungi, and bacteria in the water. These trace amounts are well below the daily required minimum of copper, so there's no way you'll get too much copper in your diet. Assuming you're not going to drink an entire swimming pool.

KDF water filters are something that you should look into when weighing your water purification options. This type of water filter is steadily gaining popularity because it has been found to be an effective water treatment option; it�s also affordable, has multiple applications and has the capacity to eliminate a wide range of contaminants without employing the use of harmful substances.
